2025 McConaghy MC86 for Sale – 85 ft – Factory, HK

The MC86 whilst remaining true to McConaghy's identifiable exterior lines and key performance attributes, is a full-custom yacht in build philosophy. This allows owners to set out the interior’s general arrangement and equipment in a way that is unique to their own requirements, with multiple bespoke options. A true "wind speed" catamaran, the MC86 has an extensive range under power as well with up to 2,000 nm at economical revs. Her bespoke carbon centre boards allow her to point much higher than other cats, yet are safely housed below decks in their carbon watertight boxes. The MC86 benefits from many of the yards in house production, with extensive use of carbon and bespoke interiors from m2Atilier. A serious, capable offshore catamaran indeed.
